Abstract
The invention discloses a low-cost landslide early warning recording device based on MEMS accelerometers. The low-cost landslide early warning recording device is composed of a microprocessor, the MEMS accelerometers, a file system management chip, a Flash storage chip, a wireless serial port receiving and dispatching module, a GSM communication module, a GPS positioning module, setting buttons, a character type LED notice board, an audible and visual alarm, a lithium-ion battery, a solar cell panel and the like. After a system is started, real-time collecting and recording of acceleration are carried out on MEMS acceleration sensors distributed on all characteristic point locations of a measured mountain slope at a preset sampling rate, data are transmitted back to the system through a wireless communication network, comparative analysis is carried out on the data and a preset acceleration threshold value, whether mountain slope vibration abnormity warning is triggered or not is judged, and warning modes are divided into GSM short message sending warning and LED character notice audible and visual warning. The low-cost landslide early warning recording device based on the MEMS accelerometers is low in cost, high in reliability, flexible in layout and especially suitable for areas where geological disasters such as landslides occur easily.
Description
Technical field
The present invention relates to Geological Hazards Monitoring early warning field, is exactly a kind of low cost fast monitored prior-warning device that is directed to landslide.
Background technology
China is that geologic hazard is occurred frequently and relate to the wide country in region, occur in every year according to incompletely statistics the domestic various geologic hazards of China, as landslide, cave in, rubble flow etc. reaches more than tens thousand of, life, property safety to the national basis facility that distributes numerous and the people have enough become serious harm.At present, for landslide, cave in, the monitoring and warning mode of the geologic hazard such as rubble flow is mainly to carry out by land resources department of government, normally Macroscopic Anomalies observation of method, and even as being used science remote sensing satellite to position to key area the in addition image recognition of taking pictures, ground displacement monitoring, deep displacement monitoring analyze judgement.But above-mentioned several main monitoring mode all needs professional and technical personnel to utilize professional instrument to operate on the spot, use cost is high and can only carry out periodicity monitoring to specific minority key area, cannot accomplish other to exist equally the area of the geologic hazard hidden danger such as landslide to carry out early warning and monitoring fully and effectively simultaneously.Therefore, need a kind of low cost in region occurred frequently, China landslide, high dirigibility, high stability and unattended small-sized mountain landslide supervision early warning system laid of being widely used in badly.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of low cost landslide early-warning pen recorder based on mems accelerometer.This device builds low cost, laying dirigibility is high, system stability strong, also can utilize GSM network to carry out Long-distance Control.
The technical solution adopted in the present invention is: comprise microprocessor, mems accelerometer, file system management chip, Flash storage chip, wireless serial transceiver module, gsm communication module, GPS locating module, button is set, character type LED notice board, audible-visual annunciator, lithium ion battery, solar panel, power management module, microprocessor respectively with mems accelerometer, file system management chip, Flash storage chip, wireless serial transceiver module, gsm communication module, GPS locating module, button is set, character type LED notice board, audible-visual annunciator, lithium ion battery, solar panel, power management module is connected.Systematic electricity is provided by built-in high capacity lithium ion battery and the circulation of external solar panel.After system starts, to preset sampling rate, the MEMS acceleration transducer that is distributed in each unique point position, tested hillside is carried out to acceleration Real-time Collection record, data compare analysis through cordless communication network return system and with default acceleration threshold values, judge whether to trigger hillside abnormal vibration and report to the police, the mode of warning is respectively to send alarming short message to default designated mobile phone terminal, with the highlighting character type LED notice board that startup is connected with device, pedestrian, vehicle near side slope are sent to real-time acousto-optic early warning.The GSM of microprocessor control gsm communication module scan round simultaneously network, identifies and processes the note containing control routine from designated mobile phone terminal automatically.The Long-distance Control of implement device running status, device also can timing or running status occur initiatively sending current device state parameter note to designated mobile phone terminal when abnormal.The note that user can specify by the self-defined increase and decrease of systemic-function button receives control end number, and can carry out custom coding to concrete note control command code.After device is retrieved, can communicates by letter with outer computer by USB connected mode and read historical record data.
Compared with prior art, the invention has the beneficial effects as follows and can effectively reduce early warning system construction cost, the dirigibility of enhancing implantation of device, raising plant maintenance efficiency.
Embodiment
For those skilled in the art can better understand technical scheme provided by the present invention, below in conjunction with accompanying drawing, example of the present invention is set forth.
Fig. 1 is structured flowchart of the present invention, and the microprocessor of example in implementing use MSP430F149, mems accelerometer to use ADXL362, wireless communication module to use 433MHZ RS485 wireless serial transceiver module, file system management chip to use CH376T, Flash storage chip to use K9GBG08U0A, GPS locating module to use RoyalTek REB-3571LP, GSM communication module to use GTM900B, solar panel to use 5V/10W specification, lithium ion battery to use 4 joint 18650 type 2500MAH specifications, button is set adopts 4 key modes (to be respectively; Function selects, confirms, on turn over, under turn over), character type LED notice board uses specification 2200mm*2200mm*100mm(double-sided display).Systematic electricity is provided by built-in high capacity lithium ion battery and the circulation of external solar panel.After system starts, to preset sampling rate, the MEMS acceleration transducer that is distributed in each unique point position, tested hillside is carried out to acceleration Real-time Collection record, data compare analysis through cordless communication network return system and with default acceleration threshold values, judge whether to trigger hillside abnormal vibration and report to the police, the mode of warning is respectively to send alarming short message to default designated mobile phone terminal, with the highlighting character type LED notice board that startup is connected with device, pedestrian, vehicle near side slope are sent to real-time acousto-optic early warning.The GSM of microprocessor control gsm communication module scan round simultaneously network, identifies and processes the note containing control routine from designated mobile phone terminal automatically.The Long-distance Control of implement device running status, device also can timing or running status occur initiatively sending current device state parameter note to designated mobile phone terminal when abnormal.The note that user can specify by the self-defined increase and decrease of systemic-function button receives control end number, and can carry out custom coding to concrete note control command code.After device is retrieved, can communicates by letter with outer computer by USB connected mode and read historical record data.
